All the Republican rage made me think about the origins of America. So much emigration out of Europe to America came out of political and religious or ethnic friction and disagreement with the regimes in Europe (and later, the rest of the world). Many, many Americans are the descendants of Europeans who came to America to practise religion or politics the way they wanted to, and not the way that their nation, or the Catholic church, or a Feudal lord wanted them to.

That same independent-mindedness and the hunger for self-governance was the force that gave the Founding Fathers the chutzpah to finally sever ties with the British Empire in 1776 and strike out on their own as an independent nation.

For those who want to strike out into the unknown in the pursuit of self-governance, such options don’t exist anymore. There is no great sparsely inhabited continent spread out (except perhaps Antarctica which is already claimed-for) for those who want to strike out on their own. Those of a libertarian temperament and with a hunger for self-governance used to come to America. But in the modern, globalised world, where can they go?

Where is the next America? Where is the next land that people seeking self-governance can emigrate to?

One prospective answer has been seasteading — moving out onto floating cities in international waters. Perhaps that will satisfy the desires of a few in the coming years, but not everyone wants to live at sea. It is another frontier, but there are many challenges to overcome. For one thing, governments have navies, and may lay claim to successful floating cities near their waters, seeking new tax revenues. Pirates may pose a similar challenge.

In the much longer term, the answer will almost certainly be leaving the planet. The only uncolonised great new continents left are the ones up in space, on other planets. There is no more effective or complete way to depart. So it is rather poetic that in the past couple of days a new Earthlike planet in a star’s habitable zone has been discovered.

Many more observations will be needed to confirm any other similarities.

But the find joins an ever-larger catalogue of more than 800 known exoplanets, and it seems only a matter of time before astronomers spot an “Earth 2.0″ — a rocky planet with an atmosphere circling a Sun-like star in the habitable zone.

The hunger for self-governance led to the birth of America. It seems highly likely, in the very long run, that the hunger for self-governance will be the force that leads not only to local space colonisation (near-earth asteroids, Mars, asteroid belt, the moons of the gas giants) but ultimately deep space colonisation. The private space industry today is already driven by libertarian-leaning individuals like Bert Rutan, Robert Zubrin and Peter Thiel.

Powerful central government drives nonconformists to find ways to escape it. If the only road to self-governance left is up into space, then that is the road that will be taken. In the end, fury over a lost election may be the thing that drives humanity to the stars.
